Beautiful chair, it seems sturdy but the "cushion" on top is in a very awkward position in relation to the backrest, resulting in my neck bending (I've been using it since yesterday and it already hurts) without a cushion or something to support the neck, you will have a problem. Other than that, the first impressions are positive.

Edit: I've had it for 1 week and I've removed the head support because it's unbearable, it's completely uncomfortable and painful for the neck. Secondly, the mesh is as tight as it should be in my opinion, resulting in it not being able to support the spine at all. Also, the foam of the seat has already "sunk" and it feels like I'm sitting on wood, resulting in pain after 2 hours (if not less...) and it's unbearable... also the armrests have such thin foam that I feel the plastic on my bone... beautiful chair but that's it. Not ergonomic at all, nor that durable. It definitely wasn't worth the money, I wish I had spent a little more to get a branded and more comfortable one... I do not recommend it.

Edit 2: It was wobbling, and now it has started to creak. I haven't had it for long (1 week), I'm not overweight (85 kg), nor am I abusing it. But it's still having problems! STAY AWAY!!!! If I hadn't spent money, I would definitely burn it! I will send their product back to get my money back
